DisplaySwitch is a useful feature in Windows that allows users to manage multiple displays efficiently. Whether you're using a laptop with an external monitor or setting up a multi-monitor desktop, DisplaySwitch can help you switch between different display modes quickly. This article will guide you through using DisplaySwitch via the Command Prompt (CMD) and other methods in Windows.

Understanding DisplaySwitch

DisplaySwitch is a command-line utility in Windows that allows users to change the display mode of their monitors. It is especially useful for presentations or when working with multiple monitors. The utility enables users to switch between the following display modes:

1. PC screen only: Displays content only on the primary monitor.
2. Duplicate: Shows the same content on all connected monitors.
3. Extend: Extends the desktop across all connected monitors.
4. Second screen only: Displays content only on the secondary monitor.

How to Execute DisplaySwitch via CMD

To use DisplaySwitch via the Command Prompt, follow these steps:

1. Open Command Prompt: Press Win + R, type cmd, and press Enter.

2. Execute DisplaySwitch Command: Use the following commands to switch between display modes:

   • PC screen only:

     displayswitch.exe /internal

   • Duplicate:

     displayswitch.exe /clone

   • Extend:

     displayswitch.exe /extend

   • Second screen only:

     displayswitch.exe /external

Practical Examples

Here are some practical scenarios where DisplaySwitch can be useful:

• Presentations: When giving a presentation, you might want to duplicate your screen so that both you and your audience can see the same content. Use the /clone option to achieve this.

• Productivity: For enhanced productivity, extend your desktop across multiple monitors using the /extend option. This setup allows you to have different applications open on each screen.

• Focus: If you want to focus on a task without distractions from other screens, use the /internal or /external options to limit the display to one monitor.

Apart from using CMD, you can also switch display modes using the Windows interface:

1. Keyboard Shortcut: Press Win + P to open the Project menu and select your desired display mode using the arrow keys and Enter.
2. Settings: Go to Settings > System > Display and choose the display mode under the "Multiple displays" section.
